Facebook is not the first social network but it is the most popular one. There have been many other social networks before Facebook and while some of them were popular at some point in time, none could reach the popularity of Facebook. In addition to keeping in touch with your friends, Facebook can be (and is) used for business. You can use it to promote your products and services, to acquire new clients, or to get traffic to your site.
Like Twitter, Facebook is just one of the many ways to get some traffic to your site. Many marketers believe that it is just a matter of time for the traffic from Facebook, Twitter and the other major social networking sites to surpass the traffic their sites get from Google.
While this time might come, don't take this as a promise that even if you do everything right, Facebook, Twitter, or any other similar site will do traffic miracles for you. For some people Facebook works like a charm, for others it doesn't work at all. The same applies to Twitter. You can't know in advance if Facebook and/or Twitter will crash your server with traffic. Just try both and see which one (if any) works for you.
Unlike Twitter, which is very simplistic, Facebook offers more possibilities. Yes, you might need more time in order to explore all the possibilities and take advantage of them but hopefully these efforts will have a great return in terms of traffic. Here are some tips that can help you turn Facebook into a traffic monster:

1.Your profile is your major weapon

As with Twitter and any other social network, if you don't make your profile interesting, you will hardly become popular. Give enough background information for you and don't forget to make your profile public because this way even people, who don't know you, when they encounter your profile, they might become interested in you and become a supporter of yours.

2.Include information about your site on your Wall and in the photo gallery

Facebook gives you the opportunity to write a lot about you and your endeavors, as well as to include pictures, so use all these opportunities to build interest in you and your products. It is even better to post videos and fill in the other tabs, so if you have something meaningful to put there, just do it.

3.Build your network

As with other social networking sites, your network is your major capital. That is why you need to invite your friends, acquaintances, and partners and ask them to join as your supporter. You should also search for people with interests similar to yours. However, don't be pushy and don't spam because this is not the way to convince people to join your network.

4.Post regularly

No matter how interesting the stuff in your Facebook profile is, if you don't publish new content regularly, the traffic to your Facebook profile (and respectively the Facebook traffic to your site) will slow down. If you can post daily, it is fine but even if you don't post that regularly, try to do it as frequently as you can. If nothing else, updating your status regularly is more than nothing, so do it.

5.Be active

A great profile, an impressive network, and posting regularly are just a part of the recipe for success on Facebook. You also need to be active – visit the profiles of your supporters, take part in their groups and other initiatives, visit their sites. You are right that all this takes a lot of time and you might soon discover that Facebooking is a full-time occupation but if you notice an increase in traffic to your site, then all this is worth.

6.Arrange your page

Unlike other social networks, Facebook gives you more flexibility and you can move around many of the boxes. If you put the RSS feed with the links to your blog in a visible space, this alone can generate lots of traffic for you.

7.Check what Facebook apps are available

Facebook apps are numerous and new and new ones are released all the time. While many of these apps are not exactly what you need, there are apps, which can work for you in a great way. For instance, MarketPlace widget/plugin or Blog Friends widget are very useful and you should take advantage of them. You can also use the widgets for crossposting (i.e. posting directly on Twitter from Facebook) because this saves you time.
